if possible I would give 10 stars...5 for the product and 5 for the support.
Bridging joomla and phpbb is not the easiest job and there are lot solutions, but this one works best and has lot´s of useful features.
Using this and other products of the company for more than a year now and I am more than satisfied.
The support is as professional as one can imagine. The developer saved my... more than once...no matter if it was a dumbo mistake on my end or some probs with the server/3rd party components.
I will continue using this product and add/buy others from him because this guy knows what he is doing and is the money more than worth. As a matter of fact I would even pay more if he asks for :-)
A clear recommendation for everyone who uses Joomla and phpbb-forum.
